Conformance to `Layer` protocol
  • id

    Unique layer name

    Declaration

    Swift

    public var id: String

  • Rendering type of this layer.

    Declaration

    Swift

    public let type: LayerType

  • An expression specifying conditions on source features. Only features that match the filter are displayed.

    Declaration

    Swift

    public var filter: Expression?

  • Name of a source description to be used for this layer. Required for all layer types except BackgroundLayer, SkyLayer, and LocationIndicatorLayer.

    Declaration

    Swift

    public var source: String?

  • Layer to use from a vector tile source.

    Required for vector tile sources. Prohibited for all other source types, including GeoJSON sources.

    Declaration

    Swift

    public var sourceLayer: String?

  • The slot this layer is assigned to. If specified, and a slot with that name exists, it will be placed at that position in the layer order.

    Declaration

    Swift

    public var slot: String?

  • The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.

    Declaration

    Swift

    public var minZoom: Double?

  • The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.

    Declaration

    Swift

    public var maxZoom: Double?

  • Whether this layer is displayed.

    Declaration

    Swift

    public var visibility: Value<Visibility>

  • Increase or reduce the brightness of the image. The value is the maximum brightness.

    Declaration

    Swift

    public var rasterBrightnessMax: Value<Double>?

  • Transition options for rasterBrightnessMax.

    Declaration

    Swift

    public var rasterBrightnessMaxTransition: StyleTransition?

  • Increase or reduce the brightness of the image. The value is the minimum brightness.

    Declaration

    Swift

    public var rasterBrightnessMin: Value<Double>?

  • Transition options for rasterBrightnessMin.

    Declaration

    Swift

    public var rasterBrightnessMinTransition: StyleTransition?

  • Defines a color map by which to colorize a raster layer, parameterized by the ["raster-value"] expression and evaluated at 1024 uniformly spaced steps over the range specified by raster-color-range.

    Declaration

    Swift

    public var rasterColor: Value<StyleColor>?

  • When raster-color is active, specifies the combination of source RGB channels used to compute the raster value. Computed using the equation mix.r * src.r + mix.g * src.g + mix.b * src.b + mix.a. The first three components specify the mix of source red, green, and blue channels, respectively. The fourth component serves as a constant offset and is not multipled by source alpha. Source alpha is instead carried through and applied as opacity to the colorized result. Default value corresponds to RGB luminosity.

    Declaration

    Swift

    public var rasterColorMix: Value<[Double]>?

  • Transition options for rasterColorMix.

    Declaration

    Swift

    public var rasterColorMixTransition: StyleTransition?

  • When raster-color is active, specifies the range over which raster-color is tabulated. Units correspond to the computed raster value via raster-color-mix.

    Declaration

    Swift

    public var rasterColorRange: Value<[Double]>?

  • Transition options for rasterColorRange.

    Declaration

    Swift

    public var rasterColorRangeTransition: StyleTransition?

  • Increase or reduce the contrast of the image.

    Declaration

    Swift

    public var rasterContrast: Value<Double>?

  • Transition options for rasterContrast.

    Declaration

    Swift

    public var rasterContrastTransition: StyleTransition?

  • Fade duration when a new tile is added.

    Declaration

    Swift

    public var rasterFadeDuration: Value<Double>?

  • Rotates hues around the color wheel.

    Declaration

    Swift

    public var rasterHueRotate: Value<Double>?

  • Transition options for rasterHueRotate.

    Declaration

    Swift

    public var rasterHueRotateTransition: StyleTransition?

  • The opacity at which the image will be drawn.

    Declaration

    Swift

    public var rasterOpacity: Value<Double>?

  • Transition options for rasterOpacity.

    Declaration

    Swift

    public var rasterOpacityTransition: StyleTransition?

  • The resampling/interpolation method to use for overscaling, also known as texture magnification filter

    Declaration

    Swift

    public var rasterResampling: Value<RasterResampling>?

  • Increase or reduce the saturation of the image.

    Declaration

    Swift

    public var rasterSaturation: Value<Double>?

  • Transition options for rasterSaturation.

    Declaration

    Swift

    public var rasterSaturationTransition: StyleTransition?

  • Undocumented

    Declaration

    Swift

    public init(id: String, source: String)

  • Declaration

    Swift

    public func encode(to encoder: Encoder) throws

  • Declaration

    Swift

    public init(from decoder: Decoder) throws
